I was on Byetta for approximately two years and had great results in the beginning. I too experienced tremendous stomach problems in the beginning yet they subsided with time. I must report, however, that after a couple of years this regimen lost all effectiveness and I am now on straight insulin and have been re-diagnosed as being type-1. This is rare according to my physician yet she explained that Byetta is only a temporary fix. Now I take 4 shots every day and have finally regained control.
Best regards,
Eddie
